Question

Identify the cell organelles present in animals and absent in plant cells, present in plant cells and absent in animals, present in only prokaryotes:

• A. Centriole, Cytoskeleton, Inclusion bodies
• B. Axoneme, Flagellum, Mesosomes
• C. Ribosomes, Plasma membrane, Flagellum
• D. Fimbriae, Flagellum, Mesosomes

Hint:

Remember that animal cells have centrioles and cytoskeletons, which are absent in plant cells. Prokaryotes contain mesosomes, which are absent in both plant and animal cells.

Answer 1

The Correct Option is A

To solve the problem, we need to identify the cell organelles that are found in animals but absent in plant cells, present in plant cells but absent in animals, and present only in prokaryotes.

1. Understanding the Cell Organelles:
Different cell organelles are present in various types of cells (animal, plant, or prokaryotic). The following are relevant organelles:

• Centriole: Found in animal cells but absent in most plant cells. It plays a role in cell division.
• Cytoskeleton: Found in both animal and plant cells, providing structure and support.
• Inclusion bodies: Found in animal cells, they serve as storage structures.
• Axoneme: Present in the flagella of both animal and plant cells.
• Flagellum: Found in both prokaryotes and some eukaryotic cells, like animal cells.
• Mesosomes: Found in prokaryotes, involved in cellular processes like respiration.
• Ribosomes: Present in all cells, involved in protein synthesis.
• Plasma membrane: Found in both animal and plant cells, regulates what enters and exits the cell.
• Fimbriae: Found in prokaryotes, used for attachment to surfaces.

2. Analyzing the Correct Option:
The correct answer is the one that matches the organelles found in animal cells but not in plant cells, in plant cells but not in animals, and those present in prokaryotes.

Final Answer:
The correct option is (A) Centriole, Cytoskeleton, Inclusion bodies.

Answer 2

Centrioles and cytoskeleton are present in animal cells but not in plant cells.
Inclusion bodies are also found in animal cells.
Flagellum, mesosomes, and fimbriae are not found specifically in plant cells, and mesosomes are found in prokaryotes.
